CVSS: 7.5EPSS: 1%CPEs: 7EXPL: 0CVE-2020-1597 – ASP.NET Core Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-1597
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against an ASP.NET Core web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the ASP.NET Core application. The update addresses the vulnerability by correcting how the ASP.NET Core web application handles web requests. Se presenta una vulnerabilidad de denegación de servicio cuando ASP.NET Core maneja inapropiadamente las peticiones web, también se conoce como "ASP.NET Core Denial of Service Vulnerability". A flaw was found in ASP.NET Core. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WH5FQ5VT3JGHXFXOETHCTBWJUIAPGHHT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZW4CBI26KSO3PRL3HLVVISXPPOYUHSXO https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1597 https://access.redhat.com/security/cve/CVE-2020-1597 https://bugzilla.redhat.com/show_bug.cgi?id=1861110 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-1161
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests, aka 'ASP.NET Core Denial of Service Vulnerability'. Existe una vulnerabilidad denegación de servicio cuando ASP.NET Core maneja inapropiadamente las peticiones web, también se conoce como "ASP.NET Core Denial of Service Vulnerability". An infinite loop was found in the HTTP Routing component of Microsoft.AspNetCore.App, which could be exploited by a remote, unauthenticated attacker. This flaw allows an attacker without special privileges to send crafted requests to a machine running an ASP.NET Core application, triggering the infinite loop and causing a denial of service in that application, for example, a web server. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1161 https://access.redhat.com/security/cve/CVE-2020-1161 https://bugzilla.redhat.com/show_bug.cgi?id=1827645 • CWE-400: Uncontrolled Resource Consumption •
